摘　　要：提出了一种新的含UPFC装置的电力系统动态混合仿真接口算法,算法中对UPFC采用动态相量建模,对电力系统网络则采用成熟的机电暂态仿真。仿真中UPFC并联侧采用定交流母线电压控制和定直流电容电压控制,串联侧采用定线路潮流控制。文中推导了UPFC的动态相量模型,讨论了与网络机电暂态模型的接口算法。研究分析和算例仿真表明:使用动态相量建模可精确地仿真UPFC的电磁暂态(EMT)过程,且仿真速度快;文中所提混合仿真方案能保证较快的仿真速度和优良的仿真精度,具有较好的收敛性,且可用于含UPFC等FACTS装置的系统发生不对称故障时的暂态稳定分析。A new hybrid simulation algorithm of alternative iteration is introduced to handle the interface between the UPFC and the power network. Dynamic phasors method in modeling UPFC is discussed, and then UPFC control system is also analyzed. Terminal voltage control and firing angle control of converter are adopted to keep constant the UPFC terminal bus voltage magnitude and the UPFC DC capacitor voltage respectively in shunt side control, and also terminal voltage control and firing angle control of converter are used to keep constant the real power and reactive power of the line in series side control. First results show the approximate precision between dynamic phasors model and electromagnetic transient; second results on 2-area system show the proposed UPFC dynamic model and the UPFC-network interface work very well in system transient stability analysis. Moreover, the proposed hybrid simulation scheme would be efficient in transient stability analysis with asymmetrical faults in interconnect power system including FACTS devices.
